How to Fix Dryer Error

1. IMMEDIATE ACTION: Disconnect power—overheating condition exists.
2. Remove rear panel to access heater assembly and thermal protection devices.
3. Test high-limit thermostat WP3392914 for continuity—no continuity indicates tripped/open thermostat.
4. Test thermal fuse WP3392519 on blower housing for continuity—replace if blown.
5. Inspect heating element for grounded windings (continuity between element terminal and metal housing)—replace element if grounded.
6. Verify blower wheel is intact and rotates freely—cracked wheel reduces airflow causing overheating.
7. Inspect entire vent system for blockages: clean lint screen thoroughly, check flexible hose for kinks, verify exterior vent flap operates freely.
8. Replace high-limit thermostat WP3392914 and thermal fuse WP3392519 as a set—both exposed to same overheating event.
9. Clean blower housing thoroughly of lint buildup before reassembly.
10. Test dryer with vent disconnected for first cycle while monitoring exhaust temperature with infrared thermometer—should not exceed 180°F. Reconnect vent only after verifying proper operation.
